Those of us who have a Raspberry Pi 4 have been able to verify that we can do anything with it, but it is not like a real computer. Part of the fault is an architecture that prevents us from installing, for example, the latest version of Firefox as soon as it comes out, but also that existing operating systems leave a lot to be desired. The latter will change in the future, as Canonical Has promised that Ubuntu will include official support for the Raspberry Pi 4 and the rest of the company's plates.
When Ubuntu 19.10 was released, Canonical already said that the latest boards from the raspberry company would be supported, but Eoan Ermine was released with a bug in the kernel that blocks the use of the USB ports in the arm64 image and the Raspberry Pi 4 with 4GB of RAM. Right now there is a way to fix it if we edit the file boot / firmware / usercfg.txt to limit the RAM to 3GB instead of 4GB by adding the line «total_mem = 3072»Without the quotes, but this is not what it should be and they will fix the problem soon.
A bug in the Ubuntu kernel prevents installing Eoan Ermine on the Raspberry Pi 4
On the other hand, the company that runs Mark Shuttleworth also promises full boot support of your operating system for all boards from the Raspberry Company, which includes all models of the original Raspberry Pi, Raspberry Pi 2, Raspberry Pi 3, and Raspberry Pi 4.
Canonical already offers a Ubuntu version for the Raspberry Pi that we can download from this link. It is about Ubuntu Server, a version that among the first steps after its installation it is recommended to install a graphical environment. In any case, everything will improve when the support promised yesterday is official. And it is that Raspbian is fine, but it is not the Ubuntu that we like so much.
